To make a Sack Posset
Take two quarts of Cream and boil it with Whole Spice, then take twelve Eggs well beaten and drained, take the Cream from the fire, and stir in the Eggs, and as much Sugar as will sweeten it, then put in so much Sack as will make it taste well, and set it on the fire again, and let it stand a while, then take a Ladle and raise it up gently from the bottom of the Skillet you make it in, and break it as little as you can, and so do till you see it be thick enough; then put it into a Bason with the Ladle gently; if you do it too much it will whey, and that is not good.
